Stays in company with the right clique (6)
I believe the answer is:
corset
'stays' is the definition.
(stays can refer to a corset)
'company with the right clique' is the wordplay.
'company' becomes 'co' (abbreviation).
'with' means one lot of letters go next to another.
'the right' becomes 'r' (common abbreviation).
'clique' becomes 'set' (I've seen this before).
'co'+'r'+'set'='CORSET'
'in' acts as a link.
(Other definitions for corset that I've seen before include "Tight-fitting undergarment" , "Stays" , "Tight-fitting bodice" , "Close-fitting foundation garment" , "Tight undergarment" .)
